β¦ Synopsis
We report on four unrelated cases of an Opitz trigonocephaly (C)-like syndrome with a highly characteristic combination of facial anomalies including prominent metopic suture, exophthalmos, hypertelorism, cleft lip and palate, flexion deformities of the upper limbs and multiple other anomalies. We also review two very similar published cases formerly considered to have the C syndrome. Although there is overlap, a clinical distinction from the Opitz trigonocephaly and other syndromes seems possible, and thus a specific causal entity may be postulated.

We describe the antenatal ultrasound findings of growth retardation, oligohydramnios, mesomelic limb shortness, and cardiac, renal, and hand defects in a fetus who was postnatally diagnosed as having RSH ("Smith-Lemli-Opitz") syndrome. An unusual finding was ectrodactyly of both hands.
Smith-Lemli-Opitz (SLO or RSH) syndrome is characterized by multiple congenital anomalies, mental retardation, and defective growth; it results from an inherited defect in the biosynthesis of cholesterol. Patients have elevated plasma concentrations of 7-dehydrocholesterol, the immediate biosyntheti
## To the Editor: The incidence of Smith-Lemli-Opitz syndrome (SLOS, McKusick 270 400) has been estimated to be approximately 1 in 50,000 to 1 in 20,000 births in North Americans [Kelley, 1997;Lowry and Yong, 1980]. However, the incidence greater than 1 in 10,000 in a completely ascertained newborn
